Sirach 19:17LXX

15Admonish thy friend: for there is often a fault committed.

16And believe not every word. There is one, that slippeth with the tongue, but not from his heart.

17For who is there that hath not offended with his tongue? Admonish thy neighbour before thou threaten him.

18And give place to the fear of the most High: for the fear of God is all wisdom, and therein is to fear God, and the disposition of the law is in all wisdom.

19But the learning of wickedness is not wisdom: and the device of sinners is not prudence.
